    摘要: There is provided a method of forming an interlayer insulating film having a dual-damascene structure, a contact hole and a deep trench mask using an organic silicon film. The shape of polysilane or the like is processed so that polysilane is used as an interlayer insulating film having a dual-damascene structure to control the shape and depth and prevent borderless etching which must be solved when a trench is formed. Polysilane and an insulating film are formed into a laminated structure so as to be integrated with each other after a dry etching step has been completed to easily form a contact hole having a high aspect ratio. The surface of polysilane is selectively formed into an insulating film so as to be used as a mask for use in a dry etching step. Polysilane for use as an anti-reflective film or an etching mask is changed to an oxide film or a nitride film so that films are easily removed. Hence it follows that a device region and a device isolation region of a densely integrated circuit can be smoothed, a self-aligned contact hole and metallization trench can be formed with a satisfactory manufacturing yield and the pattern of a gate electrode can be formed.
